Public summary reviewed

Overview#

Selleck Chemicals (Selleck Chemicals LLC, Houston, TX) is a long-running institutional life-science reagent supplier — primarily small-molecule inhibitors — that also sells a substantial catalog of research peptides and advertises custom peptide synthesis, all strictly Research Use Only / non-cGMP per its Terms. Corporate transparency is comparatively strong for this directory: the legal entity, HQ address of record (14408 W Sylvanfield Drive, Houston, TX 77014), phone/fax, and sales/orders/info emails are published consistently across its Terms, SDS documents, and product pages, and the domain dates to 2008-09-23. Gaps are specific, not structural: Texas SoS/Comptroller standing, formation date, and registered agent could not be retrieved via text fetch in this pass (refresh items, not adverse findings); the only named principal (President Dean Henry) rests on a single Tier 3 aggregator; and a second Houston address (77054 / S Loop W) in third-party listings is unexplained and sits awkwardly with the 'near Texas Medical Center' HQ description. All defined regulatory searches (FDA warning letters, recalls, import alerts, FTC, state AG, criminal/injunctive) returned No Record Found in the defined search. One material civil case exists: Celgene Corporation v. Selleck Chemicals LLC (D.N.J., filed 2015-12-24), alleging trademark infringement in the sale of lenalidomide/apremilast under the REVLIMID®/OTEZLA® marks and seeking injunctive relief — disposition not established in this pass. Testing disclosure is extensive but entirely in-house: per-batch HPLC/1H-NMR/MS/microanalysis with downloadable batch COAs (independently spot-checked September 2026, Batch S528502 at 99.9%), no independent laboratory of record and no lab verification portal. Commercial terms are published and buyer-favorable on their face: 7-day unconditional / 365-day quality returns with free return shipping, free shipping over USD 500, overnight shipping. No High/Critical severity findings; the Celgene litigation is the notable historical finding.

Relevant Civil LitigationCelgene Corporation v. Selleck Chemicals LLC et al, Case 2:15-cv-08872-WJM-MF (U.S. District Court, District of New Jersey), filed 2015-12-24 — trademark infringement / unfair competition. Celgene alleged the 'Selleck Defendants' marketed and sold lenalidomide and apremilast using Celgene's REVLIMID® and OTEZLA® marks without authorization, and prayed for preliminary and permanent injunctive relief, a finding of infringement/dilution/false designation, and destruction of infringing materials. Outcome/disposition was not established in this pass; no later peptide-vendor litigation (including the 2026 Lilly suits) naming Selleck was found.

Testing and COA Evidence#

Public COA AvailabilityCOAs are publicly downloadable — the vendor's Quality Control page states the Certificate of Analysis (COA), HPLC, MS, and NMR spectra for the buyer's specific batch can be downloaded directly from the website, and product pages carry COA links alongside SDS and Datasheet links with a stated batch and purity (e.g. Cholic acid, Batch S374201, Purity 98.58%).

HighSource: Selleck Chemicals — Quality Control page

Batch / Lot SpecificityEstablished — QC data is batch/lot-specific: product pages state a specific Batch number and purity per product (e.g. Batch S374201; Batch S315401, Purity 99.99%; Datasheet Batch S699904), and the Quality Control page illustrates HPLC and 1H-NMR for a named lot (S7963, Lot 9). A September 2026 third-party buyer guide independently inspected a batch-specific COA (Batch S528502, 99.9% HPLC, NMR consistent with structure).

ModerateSource: Selleck Chemicals — Cholic acid product page (Quality Control: Batch S374201, Purity 98.58%; COA/SDS/Datasheet links)

Independent Laboratory IdentityNo independent laboratory is identified — testing is represented as in-house. The vendor attributes QC to its own 'Quality Inspection Department' / Selleck labs (HPLC, 1H-NMR, MS, microanalysis/elemental analysis), and a third-party buyer guide states expressly: 'Selleck publishes its own lot QC; not independent third-party testing.' No external lab is named on the pages fetched.

ModerateSource: Selleck Chemicals — Quality Control page

COA Verification StatusNot verifiable through an independent portal in this pass — COAs are downloadable from the vendor's own site, but no issuing-lab verification lookup exists because testing is in-house (see independent_laboratory_identity), and no third-party verification attestation for Selleck COAs was found beyond a buyer guide's inspection of one batch COA (S528502).

ModerateSource: PeptidePub — Anageninc vs Chemyo vs Selleck Chemicals Buyer Guide (reviewed 2026-09-18; Batch S528502 COA; in-house lot QC, not independent testing)

Test RecencyCurrent — batch QC is presented alongside the live catalog, and the most recent independent inspection found in this pass is September 2026 (PeptidePub buyer guide, 2026-09-18 store check, Batch S528502 COA). Product pages crawled in this pass show current batches and 2025-2026 literature citations. No stale-COA pattern was established; per-product COA dates were not individually sampled for the peptide catalog in this pass.

ModerateSource: PeptidePub — Anageninc vs Chemyo vs Selleck Chemicals Buyer Guide (reviewed 2026-09-18; Batch S528502 COA; in-house lot QC, not independent testing)

Testing CoverageVendor-stated coverage is every batch: the Quality Control page states that for every single batch it performs HPLC (purity, typically >99%), 1H-NMR (structure), and microanalysis (elemental composition), comparing each new batch against a 'Gold Standard' reference, across a catalog the vendor describes as 120,000+ inhibitors/agonists and 8,000+ bioactive small molecules plus the peptide catalog. Independent coverage is limited to spot inspections (e.g. one batch COA in the September 2026 buyer guide); the every-batch claim is a vendor representation, not independently audited.

ModerateSource: Selleck Chemicals — Quality Control page

Evidence ConsistencyTesting and commercial claims are internally consistent across the current site (per-batch HPLC/NMR, downloadable COAs, RUO-only Terms, 365-day quality guarantee repeated verbatim on datasheets). Three documented tensions: (1) founding-date claims conflict across sources — vendor 'Founded in 2010' vs trademark first use 2009 vs domain 2008 vs an aggregator's 'Founded 2005'; (2) the 'near the Texas Medical Center' HQ description does not match the 14408 W Sylvanfield Dr (77014) address of record, while a second Houston address in the 77054/S Loop area appears in third-party listings (see address_consistency); (3) extensive QC marketing describes in-house testing only — no independent lab stands behind the COAs. No falsified-evidence indicators were found.

Payment, Refund and Shipping#

Accepted Payment MethodsPartially established — credit cards are accepted (the Return Policy provides refunds 'applied to your original credit card'), and institutional purchase-order (PO) ordering is supported (the return process asks for a PO Number or tracking number). A third-party buyer guide characterizes checkout as an 'institutional checkout or quote workflow' with no public retail price exposure for some items. No fuller public payment-methods list (e.g. wire/ACH terms) is published on the pages fetched, and the checkout flow itself was not inspected via text fetch.

LowSource: Selleck Chemicals — Return Policy

Refund / Return PolicyUnconditional return within 7 days of receipt (the dedicated Return Policy page frames the 7-day window as 7 business days for logistics-related issues); for product quality issues (product- or protocol-related), returns are accepted within 365 days of the original purchase date. Pre-authorization is required before shipping items back; items must be in original packaging and original condition; return shipping is free (vendor covers logistics/cost); refunds are credited to the original credit card within 7 days after inspection/approval, plus 2-10 business days bank posting. Policy applies only to purchases directly from Selleckchem or authorized distributors, and the same text is repeated on product datasheets site-wide.

HighSource: Selleck Chemicals — Return Policy

Shipping & Fulfillment RepresentationsProduct pages advertise 'free shipping over USD 500', 'unconditional return', and 'overnight shipping'; the About Us page states the Houston HQ 'ensures next-day delivery for our North American customers' with local-inventory hubs in Germany (EU) and Japan (same-day shipping in Japan). Datasheets state products are transported at room temperature, with vendor stability testing representing that one month at normal temperature does not affect powder-product biological activity.

Terms / Policy StabilityIntake pass — no policy-change history can be diffed yet. Current Terms are comprehensive and long-form: Research Use Only / non-clinical use, non-cGMP unless the CoA states otherwise, qualified-personnel handling, warranty limited to conformance with catalog/CoA description at shipment, liability capped at the product purchase price, Texas governing law with exclusive Houston, Texas courts. The return-policy text repeated on datasheets appears longstanding and uniform across products crawled. Future refresh cycles can diff Terms and Return Policy pages directly.
